ApplicationfiledJanuary 30,1902. SerialNmghglz. (No ads To all whom tit-may concern: I t Be it known that I, WILLIAM SoHLUTEa, a

' citizen of the UnitedqStates, residing at Aplington, in the county of Butler and State of Iowa, have invented a new andfuseful Draft- Equalizer, of which the following is a specification.

This invention relates to draft-equalizi'n g means, and has for its object to provide improved means of this character which isespecially adapted for application to corn-harvesting machinesand arranged to place the draft centrally and in rear of the cutting apparatus thereofand also to dispose the draftanimals so that one of them "may'travel be tween the rows and the others upon the stubble side of the field without interfering in any manner whatsoever with the 'cuttin g apparatus. m e

A further object, is to have the draft-equalizer complete in itself, so that it maybe applied to any ordinary type of corn-harvester.

without altering or changing the same and without interfering with the cutting apparatus and the draft connections between the same and the ground-Wheels of themachine.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanyingdrawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details maybe madewithin the 'the'scope of the 1 claims without departing from the spirit or sacrificing any'of the advantages of the invention. 1 e

In the drawings, Figure l is a planview illustrating the application ofthepresent invention to a corn-harvesting machine. Fig.

1 2 is a perspective View of a draft-equalizing apparatus constructed"and arranged inaccordance with the presentinvention. 1

Like characters ofreference designate cor responding parts "in bothfigures of the drawings. 1 In carrying out the present invention there is provided a maindraw-bar 1', which is'fulcrumed centrally betweenthe top and bottom members 2 and 30f an attaching-bracket by means of a removable bolt 4:. Each of the bracket members is in the form of a flat metallic strap or bar, the central portion'of which is bent or offsetdownwardly, thereby providing terminal cars 5, which are provided with corresponding bolt-openings 6,;wherebv the device is connected to the frame of a corn-1 harvesting machine, as,will be hereinafter des ibe 1 To, one end of the draw ba rthere is 15 80151 its outer-end with a pair of superposedpiv 'otally-connected links. 8,: which embrace a whiflietree' 9 and are connected-thereto;by means of asuitablepiv0t fastening 10. a

60 a connected a draft-rod '7, which is provided at i A draft-rod 11,*which is shorter than the red I 7, is loosely connected to theopposite end of the draw-bar and has its forward end-loosely connectedto the free end of-anf evener bar' a 17. 5. outerside of the rod'and has its outer end a 12, which lies transverselyand wholly at the pivotally connected, as at 13, to the central 1 portion of a yoke-shaped bracket 14, each end a of which is provided witha perforated pendent attaching-ear 15;"

neoted to the middle of, the evener-bar by meansof a pair of links 17, and the ends of. l

the do'ubletree are providedwith tive whiffletrees 18 and 19." p 1 To illustrate the application of the respecthe'present apparatus to a corn-harvestingmachine, a

portion of the frame ofsuoh a-machine has. 1 been illustrated at 20, said frame having thecross-bars 21 and 22 and theusual cutting apparatus 23, which is driven from one i v of the wheels of the machine in the usual manner." The members 2 and 3 ofthefattaching-bracket are. secured to the central portions of, the respective cross-"bars 2l 'and 22,the latterbeing embraced between the corresponding attaching-ears of said bracket members, wherebythe fulcrum of the drawa bar 1 islocated in rear of and centrally with respect to the'cuttingapparatus, and the draft-rods 7 and 11 lie Wholly at theopposite its pendent ears 15 applied to the outer side of the pole or tongue 26, which is connected, 7 as usual, toone side of: the franl'eof the nia- In 'front'of the evener-bar1'2 there is proa vided a doubletree16,'which is pivotally con chine, said ears being held in place by means of suitable bolts 27, piercing the tongue or pole. The bracket 14 and the evener-bar 12 are proportioned so that the links 17 or the center of the doubletree l6 lies centrally above the tongue 26, so that the whiflietrees 18 and 19 may be disposed equally at opposite sides of the tongue and in such position that the draft-animals connected thereto may pass between the stubble-rows, it of course being understood that the draft-animal connected to the whifiletree 9 is so disposed as to travel between the two outer rows of the corn, whereby the animals do not interfere with the outer row of corn, which is being acted upon by the cutting apparatus of the machine.

It will here be noted that besides equalizing the draft of the three animals the main connection "is made in rear and disposed centrally with respect to the cutting apparatus, whereby the draft connections do not interfere With said cutting apparatus, and all lateral strain, such as is common when the animals are hitched to the pole only, is effectually obviated, and in: consequence of the evenly-disposed draft the cutting apparatus operates more effectually and does not tear and twist the corn, as heretofore.

In order that the lateral movement of the draft-rods 7 may be limited, a suitable guideloop 28 receives the intermediate portion of this rod and is pivotally connected to a bracket 29, which in turn is mounted upon the adjacent guard 25 of the cutting apparatus,-thereby to prevent the adjacent animal from straying too far toward the outer side of 'the machine.

VVhat I claim is-- 1. In a draft-equalizingapparatus, the combination of an intermediately fulcrumed draw-bar, the fulcrum of which forms the point of application of the draft to a vehicle, a draft connection applied to one end of the draw-bar, a doubletree connected to the other end of the draw-bar and otherwise independ ent of the first-mentioned draft connection, and an equalizing deviceincluded in the connection between the doubletree and the drawbar and forming the sole support for the doubletree.
